Note: Many disorders can affect the digestive tract. Some can have symptoms that may be similar to or overlap with gastrointestinal (GI) functional or motility disorders. These will have uniquely identifying features which differentiate them from functional GI or motility disorders.

Celiac Disease What You Need to Know

Did you know more than 2 million Americans have celiac disease but most of them don’t know it?

What is celiac disease?

Celiac disease damages the small intestine. People with celiac disease can’t eat gluten, a protein found in wheat, rye, and barley and in some products such as vitamins and lip balms.

When people with celiac disease eat gluten—even a tiny amount—their body’s immune system reacts to the gluten by attacking the lining of the small intestine. When the lining is damaged, the body cannot get the nutrients it needs. Over time, celiac disease can cause anemia, infertility, weak and brittle bones, an itchy skin rash called dermatitis herpetiformis, or other health problems.

People with celiac disease don’t always know they have it because they may not feel sick. Or if they feel sick, they don’t know celiac disease is the cause. Either way, gluten is damaging the intestines as long as a person with celiac disease continues to eat it.

Who gets celiac disease?

Celiac disease often runs in families. You are more likely to develop celiac disease if you have a parent, brother, or sister who has it. Both adults and children can have the disease.

How can I tell if I have celiac disease?

If you have celiac disease, you may have some of these symptoms:

stomach pain

gas

diarrhea

extreme tiredness

change in mood

weight loss

an itchy, blistering skin rash

slowed growth

Celiac disease can be hard to diagnose because its symptoms are like those of many other diseases. Some people don’t have any symptoms. Your doctor can do tests to find out if you have celiac disease.

What can I do about celiac disease?

The only treatment for celiac disease is a gluten-free diet. Your doctor or a dietitian can help you learn how to choose gluten-free foods. If you avoid gluten in your diet, your small intestine should heal.
